DRAG DEVICE'FOR SPINNING- MACHINES.

T all ivhom it may concern:

Be itiknown that we, FREDERICK WILLIAM GONSTAN'LINE and THOMAS -GEORGE KAY, subjects of the Kingv of Great Britain, and residents, respectively, of Kensington Road, St. Annes-on-Sea, in the county of Lancaster, and 54 Back Cheapside, Bolton, in the samecounty, England, have invented a certain new and useful Improvementin Drag Devices for Spinning Machines,-of which the followin description, ,having reference to the accompanying .sheet of drawings, is a specification. v a

Our invention relates to improvements in spinning, doubling, twisting and like machines ,used in the productlon ofyarnsor 7 threads of fibrous substances and particularly tomeans for regulating the-drag on the spindles in. such machines. The class of drag devices to which our inventionespecially relates is that wherein centrifugally acting rolling devices are mounted ondiscs fixed :upon .loosely mounted spindles, and operating in conjunction with weights, as set .forth in our patent specification No. 121-142. In the said patent specification centrifugal rolling devices are employed which are ,free to move in any y direction either radially or in a spindle in conjunction with which they operate, and we have found that it may be 'pref-. erable or desirable to employ rolling devices which are constra ned to follow a certain path radially when brought into'operation and in some cases .to be entirely prevented from moving radially, although such rolling devices act in .a centrifugal manner. Our present invention therefore consists in the employment of improved devices whereby when these centrifugally acting means are allowed radial movement, guiding devices are made use "of to constrain-them to follow certain paths. Other means are also employed whereby the rolling devices are free tozrotate but are prevented from moving'iradially relatively to their-support. We also employ, in an alternative arrangement, conical parts mounted upon the spindles, or a series .of discs of different diameters, whereby they are enabled to pick up or be acted upon by series of weights. Where weights are employed which are gradually brought into action with these rolling devices =we employ improved meansfor operating same, :these improved means consisting Specification of Letterst Patent.

c for rail d and rotated in any appropriate mannerat a high rate of speed, the movement of said spindles through saidflyers d' regulating the winding of the yarn thereon; Or we may traverse the fiyers (Z over. the spln dles a for the same purpose.

It is well known that at the commencement of the winding of yarns upon the bare spindle or upon thin tubes mounted thereon that very little retardation should be exercised on said spindles at this time, andthat drag light enough at the commencement of the winding operations and these rolling devices consist of balls .7; resting upon discs of fixed uponthe spindles af- Inecnj nc: tion with these rolling devices'wwemay employ weights or covers Z0 'whichmerely rest upon the balls orrolling devices '00 shown. 1 by Fig. *6, 'although we preferablyjemploy' a series of'weights in f as hereinafter'described;

In our former specification above referred f to the rolling devicesftherein described were allowed-tree movement over the surfaces 0f :the discs-upon 'which they were mounted,

however we now'findthat it maybe preferable to confine them in theirmovementrelati'vely to the spindles ia, consequently instead of discs we may employ arms nhaving channels n for the reception of the balls or rolling devices 00, these being capable of occupyinrr central positions in proximity to dies 6; orfpositions at theend of the grooves or'guides n these latter positions being occupiedimmediately the rotations of the machineare commenced, thus they act in a centrifugal manner and may in certain cases be employed along with covers 72 or with the series of weights hereinafter described.- In Figs. 7 andj8 we have illustrated a series of balls :2 which are allowed a slight movement bodily away from the spindles a, such movement being controlledby theparticular construction of the" carrier 0,

In Figs. 12 and 13 we have shown a carrier 0 for the'balls w, whichallows 'them simply to rotate and not "move' bodily toward andfrom the spindles 7), so that such balls w although acting in a manner'cen trifugally'are not allowed movement which is usually caused by. such centrifugal action. In the device illustrated by'Figs. 5 "and 6, the radially disposed guiding grooves 77) are formed in thedisc a instead of being made in the arms a as shown by Fig; 9, and they answer the same purpose; Figs. 10 and 11 show merely a groove a? formed'in the disc a this allowing the balls a to move freely in a directionconcentric .also'relatively to the rails 22 and c.

to'the two rails "b and 0 connection therewithother weight 8 with the spindle movement. w a

vIntervening between the rails b and c is another rail 8 which has vertical movement transmitted to itsimultaneously with and a by preventing radial rail 8 carries the weighting 7 devices herein after described and its movement relatively regulates thebringing into action of the weighting devices and the length of time inj-which they operate; The rail 'c rests uponthe collars g fixed on the pokers 9 while the railfb is supported by the cross pieces b of theb'ars b theS-latter being connected by the links r with the. blocks'g on the pokers 9, other links r con necting thebars -6 with the rail c.-"The- This bars b have horizontal movement transmitted to-them as well as vertical movement, and it is the transmissionof this horizontal movement thereto that causes its movement f relatively to the rails b and '0. This horizon tal movement of the bars 6 is eflected, by the camiti mounted on ashaftorspindle 15 5 rotated by bevelgearing t t through the shaft fi and other bevel gears motion. Said cam trota'rtes in 'c'o'ntact with 251 M fromthe wheel", I 25 which forms part of'the' jordinary lift r,

b and 'thus moves the rail '8 a ramme less I distanc'efas is required by the cam t we partially counterbalance the springs 2 connected to frainewo'rkA; j. The particular weighting device illu-s hated by: Fig. 45 consists of asleeve or cup 8 restingupon asleeveds upon which screws a collar 8 resting loosely upon the rails. VV'thinthe sleeve or cup's isanother' cup '8 having a flange s at its 'upp'er end to retain same in position within said sleeve *The base sf of the cup 8 rests upon the balls'w which latter are contained in the holder 0. Resting upon the flanges of the-cup is airwhich' by means of the lateral opening 3 may be passed over the spin-' dle'a. It has a flange 8 rest upon the flange of said cup or sleeve The rail 8' as it rises and fallswill, onmoving to a certain'distance' allow the cup 8 to rest upon the balls sto exercise a certain amount of drag upon the spindles a-while when it moves a short distance lower it allows the. weights to act, on moving "still lower will bring into action the Weight of the sleeve s in this manner-"gradually 'increasing the drag upon the spindles-a. By increasing the'number of Weights any "desired drag may be exercised on said spindles m We have'only illustrated one. fornrofat its-upper endto' V I p according as the building of the cops a "In'order that too. muchiweight has notto belifted or'moved gradually,

weighting device, but it will readily be understood that any other alternative form may be made use of which will be brought gradually into action and taken out of action while varied weights which act at all times on the balls or rolling devices in an equal manner, may be employed.

e preferably arrange for the rolling devices or balls as to contact both with the supports a and the rolling devices, although in some cases we may only have said rolling devices extending through one side of their plates or guides as shown by Fig. 7.

Such being the nature and object of our said invention, what we claim is 1. In spinning, doubling, twisting and like machines, a spindle, a disc fixed upon said spindle, rolling devices mounted on said disc, means for'controlling the movementof said rolling devices and a member resting upon said rolling devices.

2. In spinning, doubling, twisting and like machines, a spindle, a support on said spindle, rolling devices mounted on. said support, means for controlling the movement of said rolling devices relatively to 1 said spindle and a member resting on said rollin devices. 7

3. Iii spinning, doubling, twisting and like machines, a spindle, a support mounted on said spindle, rolling devices mounted upon said support, means for controlling the parts which rest upon said weighting devices successively into opera- I tion.
